Jack London, also known as The Story of Jack London, is a 1943 American biographical film made by Samuel Bronston Productions and distributed by United Artists. It was directed by Alfred Santell and produced by Samuel Bronston with Joseph H. Nadel as associate producer, from a screenplay by Isaac Don Levine and Ernest Pascal based on the 1921 book The Book of Jack London by London's second wife, Charmian London.

Samuel Bronston was a Bessarabian-born American film producer, film director, and a nephew of Russian socialist revolutionary Leon Trotsky. He was also the petitioner in a U.S. Supreme Court case that set a major precedent for perjury prosecutions when it overturned his conviction.
